## Description
This PR adds logs around connection pool metrics in order to debug
memory leak issue https://github.com/appsmithorg/appsmith/issues/34028
Following metrics are logged for Get strcuture and Excute query calls:
- Acquired - It indicates number of connections acquired from pool
- Idle - Number of connections sitting idle in the connection pool
- Allocated - Number of connections active / idle in the pool
- Pending - Number of connections pending to be acquired.
This information can help us understand if connections are not being
released from the pool leading to memory leak.
